I have a series 2 rst and two days ago I had an oil pressure light come on after 350 miles of driving (the last 100 miles of motorway driving).The light comes on at idle and there are no unusual noises.Its had a new oil switch about 5000 miles ago and a new pump about the same time.Today I fitted a pressure gauge and when its hot (to the point of having the cooling fan cut in) its showing about 10 psi at 800-100rpm.The funny thing is even though the gauge is showing 10 psi the oil light isnt coming on until i stall it.Can anyone help please coz I have to travel another 350 miles tomorrow.Thanks everyone.
